as any one in england noticed this problem i have 8 yucca's in my garden and 6 of them have the same problem.They range in height from 5 feet to 10 feet high some double stem's the normal bottom leaves dry out go brown and i pull them off and it leaves the stem looking like bark , but now the bottom leaves go yellow and have started to rot and as i take them off i am left with a smooth stem on 3 or 4 of them i am now left with only 4 leaves on the plant is this due to the 4 or5 weeks of hard frost that we had this year or is it fungi and if so can anything be done for them or do i dig them up
thank you

I am not familiar with your countries conditions but I can tell you that in Iowa we grow yuccas and we get well bellow freezing for long periods of time every winter and they return fine here. The freeze does make the leaves a little mushy and we just pull them off. Then in the spring they recover and send out all new growth. Unless you are sure it is a fungus I would let them go for a little longer and watch for signs of new growth before giving up and ripping them out.

Yuccas are really tough. If they don't start leafing back out where it is bare after a month, you might try whacking it down and letting it start over.

If you get a lot of rain, yucca will rot. I have had yucca at my last house. They need full sun. Clean out the clumps thoroughly of dead leaves,cut back if needed. You may also try adding sand, peat moss and a good soil mix to aid in drainage in the area. You may have to dig up the whole clump and replant in another hole or the same hole with an amended soil mix. Check with your local garden center or plant advice organization if you continue to have problems.

once yucca blooms, it dies and develops new suckers. If you think it's fungus, you should just relocate them to another place. don't plant anything in that affected area. Yucca is frost resistant.

Start all over and dig the stems out and start developing new plants from cuttings by letting them soak in water. We have a lot of Yucca and all kinds of them. We start new plants in different ways every year. If there is a long stem, we use old milk jugs filled with water and set them out on the porch to develop roots. They don't have to have leaves. Once they develop roots we transfer them into the soil and will develop leaves very fast. We also developed new plants by just cutting the old stems into pieces and dug them under, covered with 1 inch of soil or so. Just keep the soil moist.
